Any hardware that couples with a mobile app is potentially a bad idea. Eventually, the company will stop developing that app, which means you just have to use that device without the mobile app. If it’s an RC car without a controller, you’re left with e-waste. If it’s an electric toothbrush, you can probably still use it, but with fewer features than before. Either way, it’s bad news for the user.
